12 Page 12 of 16 pages European Technical Approval PERINSUL HL - ETA-13/ Installation of the product in the works The positioning of the PERINSUL thermal break shall respect the installation requirements of the manufacturer and be in conformity with the state of the art of building masonry walls. Also all masonry dilatation joints and other constructive joints shall be respected. In the design and the calculation of the ultimate stresses, the Eurocode 6 (EN ) in local design requirements shall be respected. The PERINSUL blocks are horizontally positioned one against the other in the mortar and slightly and gently knocked with a trowel until the mortar on all slides is flowing out and a perfect adhesion is reached. Knocking or banging with the sharp edges of the trowel or other objects shall be avoided. The vertical joints in between the PERINSUL are closely positioned without mortar in between. As with all masonry, direct exposure to frost should be avoided. For the position at the bottom of the masonry wall: Upon the positioned PERINSUL blocks the first layer of bricks are fully placed into the mortar and shall be installed in such a way that the loads are reparted over the surface. spread over For the position under windows and sills: So as to prevent punctual loads, in between the PERINSUL blocks and the window a reparation (eg fibre ciment board) is to foreseen. Sills on the insulation blocks are placed in a full mortar bed. 4.4 Use, maintenance, repair As the PERINSUL -thermal break layer is integrated into the masonry, no extra attention as for maintenance or repair is necessary. Within the disposal and discharge treatment to thermal breaks can be considered on basis of the same waste/reuse procedures as for the masonry elements.
